Abstract
REFERIDA A UN PROCEDIMIENTO PARA LA PRODUCCION DE PARTICULAS DE UREA DE UNA SOLUCION ACUOSA DE UREA QUE COMPRENDE UNA ETAPA DE CRISTALIZACION, EN EL QUE LA SOLUCION SE SOMETE A EXPANSION BRUSCA EN SECO CON EL FIN DE OBTENER UREA SOLIDA CRISTALIZADA QUE CONTIENE EL PRODUCTO Y UN VAPOR QUE CONTIENE AMONIACO Y AGUA, Y POSTERIORMENTE UNA ETAPA DE FORMACION QUE COMPRENDE EJERCER FUERZA MECANICA SOBRE LOS CRISTALES DE UREA. LA SOLUCION ANTES DE LA ETAPA DE CRISTALIZACION ES CONCENTRADA HASTA OBTENER ENTRE 60% Y 98% EN PESO DE UREA Y EL TAMANO DE PARTICULA DE UREA OBTENIDO DESPUES DE LA ETAPA DE FORMACION TIENE UN TAMANO DE PARTICULA EN EL INTERVALO DE 1 MM A 10 MMREFERRING TO A PROCEDURE FOR THE PRODUCTION OF UREA PARTICLES FROM AN AQUEOUS UREA SOLUTION THAT INCLUDES A CRYSTALIZATION STAGE, IN WHICH THE SOLUTION IS SUBMITTED TO BRUSH DRY EXPANSION IN ORDER TO OBTAIN A SOLID AND CRYSTALLIZED UREA PRODUCT CONTAINING AN ELASTIC CRYSTAL STEAM CONTAINING AMMONIA AND WATER, AND SUBSEQUENTLY A TRAINING STAGE THAT INCLUDES EXERCISING MECHANICAL FORCE ON THE UREA CRYSTALS. THE SOLUTION BEFORE THE CRYSTALIZATION STAGE IS CONCENTRATED UP TO OBTAIN BETWEEN 60% AND 98% IN WEIGHT OF UREA AND THE UREA PARTICLE SIZE OBTAINED AFTER THE FORMATION STAGE HAS A PARTICLE SIZE IN THE INTERVAL OF 10 MM TO THE INTERVAL
